The chimney crown is a slab of concrete that tops the masonry chimney. The crown’s purpose is to prevent water from running into the chimney. A long winter of freezing temperatures and heavy precipitation can lead to a damaged chimney crown, and even a small crack in a masonry chimney can cause water damage to the entire system. When you notice the hint of any water in the chimney system, you should notify a professional immediately. However, the average homeowner won’t notice a water leak until it’s caused extensive hidden damage. This is why it’s important to schedule routine maintenance. If you haven’t had your chimney inspected in the last calendar year, you should do so now. It’s at this appointment that any issue with the chimney crown will be detected
